  camera / keyframe interpolation

  Posted by Wim Roegels on June 15, 2006 at 11:11 pm

  Hi,

  this is bothering me for a couple of projects now and I was everytime able to fix this, but I didn’t really know how I did it. This is a very basic question, but a hint would help me alot …

  I have the problem, that I have two keyframes controling the position of a camera in 3d space … the only value which is changing is the Z Value of the position, X and Y should keep their values. What I want to have is a ‘ease in’ for the Z value, but the others X&Y should stay as they are … is there a way to only edit ONE Value of a Positon keyframe?

  Unfortunatly – as you can see on the screenshot – X and Y change also slightly …

  Use 3 nulls: one for X, one for Y and one for Z. Using an expression, tie each position parameter for the camera to the relevant position parameter for each null. For example, tie the camera’s x-position to the X null’s x-position.

  For more info, search the COW for “null” and “expression” and “3D”. You might also want to include “Smith” as the author.

  Thanks for your answer Steve.

  I was aware of better using NULLs to control a camera in AE … but I thought I am doing something wrong.

  Strange interpolation anyway.

  Thanks again.
